The `Window` 'frame structure, lwhich ymay be .of the very simple form indicated,v is indicated as an entirety bythe numeral 13 andthe Wal'liof a ,building yto which `it is "l" applied is indicated by thenunieralll. This window frame, on its opposite sides, is pro'- vided with thecustomary outerstopstrips 15, intermediate stop' strips 16, and .inner usual, is ,arrangedto slidevin-cliannelsdorined between the s top strips 15-andf16, and the lower sash 19 is arranged to slidein the channels fornied t,betr-veen tlie stop strips 1G/and 17 The stop stripsl and'17 are removablyy held in one position, preferably inthe usualv way, said strips being set into grooves formed .in the sides ofthe Window rameandsaid stopfstrips v17 being secured to thesides 4of' the Window frameA bythe not illustrated. y

The invention applied las illustrated in Figs. 1 to 8, inclusive, Will first be described:

Flic-Window sashes ,18 and19, `iii-their' opposite vertical edges, areformedwith grooves 1,8n and 19,`i'espectively,to form clearance passages for tension rods presently to be described. The grooves 19a inthelovve'r. sash 19 preferablyrun from top to bottom thereof, vvliileftheugrooves 18a in preferably terminate ingairv at theeXpQSed lower portion ofthe outer sash. In; the lowersash, the grooves are not' exposed at their-y ends lat1the,'exteriorV erally Vspaced friction orY tension ,devices Lis' .applied tov each sash, although, for a less .F 'ONE-HALF 'ro 01mm Thevupper sash 18,;as is customary blades, y

the upper ,sash 1 8l short of the bottomsY thereof so as to prevent said slots froinleak-- at their upper ends by sash might Vbe supported by one tension device. In what is at present believed to be the preferred form of the tension device illustrated in Figs. l to 8, inclusive, each such tension device comprises a rod 20, a spring-anchoring clip 21, a tension spring 22, and a clip-anchoring sleeve 23, all of which are arranged to work in the respective grooves 18a or 19a, as the case may be. Also in this preferred arrangement, the four tension rods, of which there are two'for each sash, are rigidly attached threaded engagement or otherwise to heads 24, which, by suitable devices such as wood screws 25, are pivotally attached to the upper side portions of the window frame 13. These heads 24 are of such width that, when the sashes are raised to eXtreme positions, they will pass freely into the upper extremities of the respective grooves 18fL or 19a, as the case may be. These tension rods 20A are, therefore, freely suspended frointheii' upper ends so that they'may swing laterally, as will heree-iicient job, each inafter appear, and may oscillate slightly so that they are self-adjusting to the movements of the sashes and the cooperating spring-anchoring clips.

The tension springs here illustrated Vare closely coiled springs that are normally distorted or bent transversely, so that they tend to assume a humped or crooked formation [and so that, when telescoped onto the cooperating tension rods, they will engage the samekwith' sufficient friction to hold the respective sashes in any vertical positioninwhich they may be'adjusted. rIo cause these tension springs to move spring-anchoring clips 21 are employed and these clips, as here illustrated, are each formed from a single piece of stiff wire bent to form laterally offset axially aligned eyes or loops 21a and a laterally projecting trunnion or finger portion 2lb, which latter projects at a right angle to the a-Xis of said eyes 21a. The clip-anchoring sleeves 23l are preferably tapered and externally threaded and are slit at their outer ends so that a screw driver may be applied thereto to screw the same into seats formed in the sashes at the bottoms of the grooves thereof.

The tension springs 22 are placed between the eyes 21a of the respective anchoring clips and the rods 20 are passed through said eyes and the cooperating springs. In applying the tension devices to the sashes, assembled as just indicated, the anchoring sleeves 23 having iirst been screwed into the sashes, the trunnions 21b are inserted into the respective anchoring sleeves 23, as best shown in Figs. 3, 4; and 5, and then the upper'ends of the rods will be attached to the window fram-e by application of the wood screws 25 to the heads 24.

When the stop strips 17 and 18 are rewith the sash, theV inwardly, as indif and the said .elements 21v and 22 then slid y onto the rods 20.

Not only are the tension rods 20 freev for the above described lateral oscillatory movements, but they are free for slight oscillal tory movements in the plane of the sashes, so thatsaid rods thus suspended from their upper ends and free at their lower ends are self-adjusting to any irregularities in the movements ofthe sashes or to any inaccuracies in the construction vand manner of assembling. The feature of suspending the rods from one end only, from their upper ends, vis important because it permits the sashes, when the stop are removed, to beswung into the room or out of working positions without first detaching the sashes from the tension rods. This feature is important for several reasons. In the first place, it makes it possible toquickly remove the sashes and replace the :and preferably only strips same, and in the second place, it makes it possible to swing the sashesinto the room or out of position so that they may be readily cleaned on both sides, even while still ap- 8, inclusive, buta somewhat modified form iw:

of spring-anchoring clip is employed. The

alreadj despring-anchoring clips 26 here provided are each made from a singlev piece of wire bent to form laterally oset axially aligned eyes 26 and an anchoring eye 26'), which latter is the lower end of the clip and is anchored to the sash preferably by ascrew 27. `distorted springs 22 are placed between the aligned eyes 2Ga and the rods 20 are passed therethrough, as in the construction previously described. In this construction and in previously described, the

the construction spring-anchoring clips are pivotally anchored to the sashes so that they also are selfadjusting. The numeral 13a and 12 is also the same laslbeforeldescribed, Y,

The

Y indicates stop strips applied to the frame 13 below the i between which the distorted spring 22 is :t: selves to movements of the sashes but would applied. To pass the cooperating tension rod 20 through the spring 22 and through the lugs 29, the latter are either perforated or notched, but as illustrated, said lugs are provided with notches 3() that embrace'the rod 20. 1 c

From what has heen said, it will be understood that the invention described is ca-l pable of various modifications, all within the spirit of the invention herein disclosed. The distorted or transversely offset coiled spring, while an extremely simple device of small cost, is, at the same time, the most efficient kind of friction device for engagement with the tension rod. l

The importance of anchoring the tension i a rods with freedom for lateral swinging or shifting movements to adapt themselves to the movements of the sashes, will be appreciated when it is kconsidered that rigidly supported tension rodswould not adapt themtend to be the controlling guides for the sashes and there would, therefore, tend to be a conflict between the `guiding functions of the rods and of the sash-guiding channels. My described arrangement of the said elements affords a structure that does not need to be applied with any great care or close atrtention to afford a completely operative and satisfactory arrangement for the purposes had in view. The various features noted and those that are obvious make this simple arrangement a highly satisfactory, lowcost device foi` t-he purposes had in view.

Jhat I claim is: l. The combination with a sliding sash, of a tension rod anchored against endwise movements but free for lateral shifting movements and extended along the line of travel` of the sash, and a friction device applied to the sash and slidably engageable with said tension rod.

Q. The combination with a window frame and a sash slidable therein, said sash having a grooved vertical edge, of a friction device applied to said sash in the groove thereof, and a tension rod pivotally anchored to said frame at one end and working friction` aliy through the friction device of saidl sash.

8. The combination with la window frame and sash, of a tension rod anchored to said frame, a threaded clip-anchoring sleeve applied to said sash, a spring-anchoring clip slidable on said tension rod and having a laterally projecting trunnion seated in said anchoring sleeve,and a spring seated in said clip for travelling movements therewith and having frictional engagement with said tension rod. f s

' 4. The structure defined in claim 3 in which said spring-anchoring clip is made from a single piece of wire bent to form the laterally projecting trunnion'thereof and to form axially aligned eyes through which i said tensionrod is passed.

5. The combination with a window frame and sash slidable therein, of laterally spaced tension rods pivotally connected to said frame at one end and extended along the line of travel of said sash, said sash having friction devices applied thereto `and frictionally slidable on said tension rods, the said frame having removable stop strips which when removed permit the sash and tension rods to be swung laterally .from working positions.
